ADJUSTMENTS
Cut-Off Length Adjustment.
WARNING
The Safety Lift Lock MUST be in place when
working on the Cutter Head in the raised position.
Failure to observe this warning could result in
Serious injury or death.
CAUTION
When changing Sprockets, to modify the Cut-Off length,
the length of the chain may also have to be changed,
particularly when changing from ‘large’ to ‘small, or ‘small
to ‘large’
Incorrect chain length can result in the Idler Arm hitting
the frame causing damage to the Cut-Off Cam.
NOTE
The ‘standard’ Cut-Off length is 54 inches.
Rolls that are more than 10 inches in diameter will not
fit on the Index Conveyor.
Refer to the Sprocket Selection Chart on the following
page for available Sprocket Combinations.
To change Sprockets:
•
Set the Depth of Cut Cylinder fully retracted .
The Idler Arm Tension Springs ‘ A ’ will be under
‘light’ tension.
•
Carefully press down on the Idler Arm ‘ B ’, and
lift the Chain off the Idler Pulley ‘ C ’.
•
Remove the Chain from the Cam Sprocket ‘ D ’.
•
Back-off the Set Screw in the Cam Sprocket,
(early units have Taper Lock Bushings), and
remove it from the Cam Shaft.
If the sprocket combinations chosen make it necessary
to change the Roller Sprocket:
•
Remove the Bolts from the Roller Sprocket
Taper Lock Bushing ‘
E ’. Fit the bolts into the
threaded holes and tighten them to release the
Taper Lock.
•
Install the new Sprockets and refit the chain in the
reverse order to above.
•
To ensure that the Chain ‘runs straight’ on the
Sprockets and Idler Pulley, visually check that
they are in alignment.
IMPORTANT
When making changes from ‘large’ Sprockets to ‘small’,
or ‘small’ to ‘large’, it may be necessary to adjust the
length of the chain, adding/subtracting Links as required.
When fitting the Roller Sprocket, check that it is pushed
far enough onto the Roller Shaft to ensure that the Taper
Lock Bushing Bolts do not hit against the frame.
Before operating the machine, it is important to check
that there is a minimum 1 ½ inches clearance between
the Idler Arm and the Frame ‘
F ’, with the Depth of Cut
Cylinder fully extended.
